Stephen Amell is standing by his female co-stars and crew members after 19 cases of sexual harassment against "Arrow" and "Supergirl" executive producer Andrew Kreisberg were made public last week.

"Again, I echo the statements made by my friend and coworker Emily Bett Rickards, Caity Lotz, Melissa Benoist and the chorus of others that have come forward and called for a safe, progressive, equal working environment".

Mr Kreisberg, an executive producer, worked on the WB series Supergirl, The Flash, Arrow and DC's Legends Of Tomorrow.

Kreisberg is the latest Hollywood power player to be accused of sexual misconduct, with Harvey Weinstein, James Toback, Brett Ratner, and Kevin Spacey among the other names linked to the scandal sweeping the industry.

Over the weekend (10-12Nov17), it emerged Warner Bros. There were also allegations of sexual comments made toward women.

Warner Bros. has yet to reveal whether their investigation has concluded, so no result has been released yet.

Kreisberg has vehemently denied the allegations, but as the in-house investigation continues, Amell, who portrays the titular Green Arrow vigilante on TV, has spoken out to lend his support to any victims of sexual harassment or assault, offering to help them report any bad behavior to their superiors.

Page posted last Friday on Facebook that he outed her as a lesbian a dozen years ago during a cast and crew meet-and-greet for X-Men: The Last Stand, when she was 18. "X-Men" co-star Anna Paquin corroborated Page's account Friday on Twitter. Facing harassment claims, Affleck apologized last month on social media for groping actress Hilarie Burton on "Total Request Live" in 2003, and then said that he was looking at his own behavior "and making sure I'm part of the solution".

Benoist, in her tweet Sunday, said that "we all need to hold ourselves to a higher standard".

"And so this week", Benoist added, "I'll head back to work on Supergirl even more committed to being a part of changing the norm by listening when people speak up, and refusing to accept an environment that is anything less than a safe, respectful and collaborate space".
